Specification forming part of Letters Patent No. 11 ,022, dated August 15, 1371.

To all arlmm it may concern:

Be it known that I, Jenx \V. KEELY, ot'lhiladelphia, lennsywania, have nvented a new and useful Improvement in Fly-'lu "ls, ol' whieh the ibllowing' is a speeitieation:

M1 invention eonsists in arranging a flywheel on the main shat'tot' any engine or foot or horse power, imlependently, in (combination with gearing, as lu-reinal'ter deseribed, whereby I am euabled, without danger, to run the tly-wheel at a high veloeity, and aeeomplish the work of an ordinary tly-wheel with one ofnmeh less weight.

The drawing represents in full size a longitudinal vertical section of a device embodyingmy invention. i

A and 13 are uprightsqvhieh furnish bearings and support for the other parts ot'thedeviee. U is the tly-wheel, whieh is not rigidly attached to the main shaft 1), but arranged independently thereon. The hub of the fly-wheel C is a little main shaft 1).

rigidly, also, the eog'avheel IT, .Yhieh gears into the cog-wheel I, which is: rigidly attached to the K represents a eranlc, by whieh power is applied. L and M are collars, designed to keep the tly-wheel in position.

The \eloeity ot' the ily-wheel C is regulated by the proportions of the gear-wh els, which may be iuereased or diminished in diarneter at pleasure; but they must be so eonstrueted that the shaft of the geaz-wheels F'and ll'shall run parallel I with the main shaft.

The tiy-wheel may he made in any substantial manner; but I prefer to make it solid from hub to rim, rather than with spokes: or arms; and also prefer that it should be turned up true and balanced. 1

lelaiiui The tly-wheel (l, in combination with the gearwheels E F I] I, all arranged and operating in relation to shaft 1), substantially as set forth.
